Claim 2

In a time-division system wherein data signals are successively assembled into time slots during each one of a sequence of time frames, a storage system comprising: a plurality of stores, each of the stores having portions for storing data signals, each portion in each store individually dedicated to each of the time slots of the time frame and grouped with corresponding portions in other stores dedicated to the same time slot; means effective during one of the time frames for writing the assembled data signals into one of the portions of the groups dedicated to the time slot; and means operative during the next sequential time frame for simultaneously reading the contents of all of the portions of tHe group dedicated to the time slot.

Claim 3

In a time-division system, in accordance with claim 1, wherein the writing means includes means for writing successive ones of the assembled data signals into different ones of the stores.

Claim 4

In a time-division system in accordance with claim 2 wherein the means for writing includes sequencing means for defining successive ones of the stores to store successive ones of the assembled data signals.

Claim 5

In a time-division system in accordance with claim 3 and further including a source of address signals, each of the address signals accompanying each of the assembled data signals and designating all of the portions dedicated to one of the time slots and wherein the means for writing includes means responsive to each of the address signals for identifying the designated portions, and means responsive to the defining of one of the successive stores and the identification of the designated portions for selecting the portion in the defined store dedicated to the time slot.

Claim 6

A time-division system for interconnecting a plurality of incoming data channels on each of a plurality of incoming lines with a plurality of outgoing data channels on each of a plurality of outgoing lines, said system comprising: means for assembling data signals from all of the incoming channels during each one of a sequence of time frames; a group of stores associated with each of the outgoing lines, each of the stores in any one of the groups having storage areas individually dedicated to each of the outgoing channels on the associated outgoing line and individually arranged to store a data signal destined for the outgoing channel; means for writing the data signals assembled during one of the time frames and destined for the outgoing channels on any one of the outgoing lines into one of the stores of the group associated with the outgoing line, each of the data signals being written into a selected one of the areas in one of the stores; and means for distributing the data signals written into the group of stores to each of the outgoing channels on the associated outgoing line during the next sequential one of the time frames, the distributing means including means for simultaneously reading out all of the areas in the group of stores dedicated to the outgoing channel.

Claim 7

A time-division system for interconnecting a plurality of incoming data channels on each of a plurality of incoming lines with a plurality of outgoing data channels on each of a plurality of outgoing lines, said system comprising: means for assembling data signals from all of the incoming channels during each one of a sequence of time frames; a group of stores associated with each of the outgoing lines, each of the stores in any one of the groups having storage areas individually dedicated to each of the outgoing channels on the associated outgoing line and individually arranged to store a data signal destined for the outgoing channel; means for writing the data signals assembled during one of the time frames and destined for the outgoing channels on any one of the outgoing lines into one of the stores of the group associated with the outgoing line, each of the data signals being written into a selected one of the areas in one of the stores; and means for distributing the data signals written into the group of stores to each of the outgoing channels on the associated outgoing line during the next sequential one of the time frames, the distributing means including means for simultaneously reading out all of the areas in the group of stores dedicated to the outgoing channel.

Claim 8

A time-division system in accordance with claim 5 and further including a second group of stores associated with each of the outgoing lines, each of the stores in any one of the second group having storage areas individually dedicated to each of the outgoing channels on the associated outgoing line and individually arranged to store data signals destined for the outgoing channel and means for writing the data signals assembled during the next sequential time frame into selected areas in the further group of stores.

Claim 9

A time-division system in accordance with claim 5 wherein the means for writing includes sequencing means for defining successive ones of the stores in the group to store successive ones of the assembled data signals.

Claim 10

A time-division system in accordance with claim 7 and further including a source of address signals, each of the address signals accompanying each of the assembled data signals and designating one of the outgoing channels and wherein the means for writing includes means responsive to each of the address signals for identifying the areas dedicated to the designated outgoing channel, and means responsive to the defining of the store in the group and the identification of the dedicated areas for selecting the one area that the data signal is written into.
